Sea anemone inland???

Another of the weird things growing in the woods. Sorry, not the clearest of photos as it is getting dark, tomorrow promises rain so I did not want to lose it! No idea what this is, it is even the size of the anemone you get in europe, around 3-4 cm diameter. The white stuff at the back is a sort of slime.

That's amazing Ferdy, thank you!
Definately a stemonitis but as to which one is not so easy to ascertain. axifera, fusca,herbatica, pallida and splendens all appear to occur in South Africa although the nearest recorded spotting to my location is herbatica, so either we just go for Stemonitis sp. or chance it and go for Stemonitis herbatica.
